either Gapless set has worked for me. Some people claim a gapless second cannot work because it holds pressure between the top and second ring but I have a Cutlass outside that shows different. The Gapless second set is a little cheaper, but like I said the pro's recommend Gapless top.
I believe those rings are all ductile iron as well, but it's been a while so I would check on that before you hold it to be gospel.
